Keep the offset and try a drum. I went from a little Jambo to a Gateway drum(basically a pretty UDS). I miss the Jambo for the novelty factor but man once I half assed figured out this drum it is a damn fine cooking machine. Just did a comp last weekend and it went 24 hours on a basket full of lump. Never had to add fuel. Recovers quick, easy to adjust temps. Of course the best part about the drum is I can load it into the back of my truck by myself.
